Okay, so I just got my 436 yesterday and I got it loaded up with my favorites list, but in a side-by-side comparison to an almost identically programmed pro-106, it seems to be missing a lot and I don't know what I'm doing wrong. I deleted a bunch of tower sites that are nowhere near my location and that didn't help any. Should I remove all the sites except for the ones identical to my 106? I'm not expecting it to pick up everything identically, but I feel I'm missing a lot on the 436. Any ideas?
